 ============================
 
 This repository contains waveform-derived HDF5 data products, SeismicX-Cont
-metadata and documentation, validation products, examples, and code. Different
-parts of the release use different data-use terms and licenses.
-
-Waveform-derived HDF5 database products
----------------------------------------
-
-The HDF5 waveform database products are processed and structured derivatives of
-source waveform records obtained through U.S. seismic data providers. They do
-not reproduce the original NCEDC or SCEDC archive organization, and they are not
-relicensed by SeismicX-Cont under CC BY 4.0.
-
-Publication and redistribution of the processed HDF5 waveform layer have been
-clarified with the relevant U.S. seismic data providers. Use of the
-waveform-derived HDF5 products is limited to non-commercial scientific research
-under upstream-compatible data-use terms, including NCEDC-compatible CC BY-NC
-4.0 conditions where applicable. Users must comply with source-provider terms
-and cite the original SCEDC, NCEDC, CEED, and contributing-network sources as
-appropriate.
-
-SeismicX-Cont-authored metadata and documentation
--------------------------------------------------
-
-SeismicX-Cont-authored metadata schemas, documentation, manifests, validation
-summaries, figures, and reuse documentation are released under the Creative
-Commons Attribution 4.0 International License (CC BY 4.0):
+metadata and documentation, validation products, examples, and code. The
+waveform sample arrays retain upstream-compatible data-use terms; all other
+released assets use CC BY 4.0.
+
+Waveform sample arrays
+----------------------
+
+The waveform sample arrays stored in the HDF5 database are processed and
+structured derivatives of source waveform records obtained through U.S.
+seismic data providers. They do not reproduce the original NCEDC or SCEDC
+archive organization, and they are not relicensed by SeismicX-Cont under
+CC BY 4.0.
+
+Publication and redistribution of the processed waveform sample arrays have
+been clarified with the relevant U.S. seismic data providers. Use of those
+arrays is limited to non-commercial scientific research under upstream-
+compatible data-use terms, including NCEDC-compatible CC BY-NC 4.0 conditions
+where applicable. Users must comply with source-provider terms and cite the
+original SCEDC, NCEDC, CEED, and contributing-network sources as appropriate.
+
+All non-waveform release assets
+-------------------------------
+
+Except for the waveform sample arrays described above, all assets in the full
+and mini SeismicX-Cont releases are released under the Creative Commons
+Attribution 4.0 International License (CC BY 4.0). This includes metadata and
+schemas, coverage indexes, event and phase annotations, response metadata,
+manifests, validation summaries, automatic-pick and consensus-candidate
+products, figures, documentation, scripts, notebooks, and reusable utilities.
+Source-provider attribution and citation requirements remain applicable to
+source-attributed fields and derived records.
